We divide 743223 by 99
The aim is to understand the frequency of 99 in 743223.

Let's proceed to step 1:
The number 99 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 99

Let's proceed to step 2:
If we divide 74 by 99, we get 0 and a remainder of 74.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 74, we end up with 74.
Take the next digit (3) from the dividend and append it to 74, then repeat: 743 / 99

On to step 3:
If we divide 743 by 99, we get 7 and a remainder of 50.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 693 from 743 and we're left with 50.
Take the next digit (2) from the dividend and append it to 50, then repeat: 502 / 99

Let's proceed to step 4:
99 can be fit into 502 5 times, resulting in a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
The remainder is 7 after subtracting 495 from 502.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 99

Going ahead to step 5:
The number 99 fits into 72 0 times, leaving a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 750.0
The remainder is 72 after subtracting 0 from 72.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 99

Advancing to step 6:
723 divided by 99 is 7 with a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 7507.0
The remainder is 30 after subtracting 693 from 723.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
99 can be fit into 300 3 times, resulting in a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 7507.3
The remainder is 3 after subtracting 297 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
The number 99 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 7507.3
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
If we divide 300 by 99, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 7507.303
Subtract 297 from 300 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
If we divide 30 by 99, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 7507.303
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
99 can be fit into 300 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 7507.30303
If we subtract 297 from 300, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 12:
30 divided by 99 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 7507.30303
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
300 divided by 99 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 7507.3030303
Deduct 297 from 300 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 14:
When dividing 30 by 99, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 7507.3030303
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 7507.3030303 with a balance of 3e-08.
